2019-09-05habanalabs: explicitly set the queue-id enumerated numbersDotan Barak
When looking at kernel log messages and when debugging user applications, we only see the queue id. This patch explicitly set the queue id in the queue enumeration which will be helpful for finding the queue name when we have its id.

They clean up the names of variables , structs and struct members, convert can_rx_register() to use max() instead of open coding it and remove unneeded code from the can_pernet_exit() callback. The next three patches are also by me and they introduce and make use of the CAN midlayer private structure. It is used to hold protocol specific per device data structures. The next patch is by Oleksij Rempel, switches the &net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that it can be used from NAPI (soft IRQ) context. The next 4 patches are by Kurt Van Dijck, he first updates his email address via mailmap and then extends sockaddr_can to include j1939 members. The final patch is the collective effort of many entities (The j1939 authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the CAN networking stack. SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world.

2019-09-05kprobes: Prohibit probing on BUG() and WARN() addressMasami Hiramatsu
Since BUG() and WARN() may use a trap (e.g. UD2 on x86) to get the address where the BUG() has occurred, kprobes can not do single-step out-of-line that instruction. So prohibit probing on such address. Without this fix, if someone put a kprobe on WARN(), the kernel will crash with invalid opcode error instead of outputing warning message, because kernel can not find correct bug address.

Sysfw provides an option for requesting exclusive access for a device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is not used, the device is meant to be shared across hosts. Once a device is requested from a host with this flag set, any request to this device from a different host will be nacked by sysfw. Current tisci driver enables this flag for every device requests. But this may not be true for all the devices. So provide a separate commands in driver for exclusive and shared device requests.

Then for omap5, we need add the missing clkctrl clock data so we can configure sgx. And we configure sgx for omap34xx, omap36xx and am3517. For am335x, we still have a dependency for rstctrl reset driver changes, so that will be added later on.

2019-09-04w1: add 1-wire master driver for IP block found in SGI ASICsThomas Bogendoerfer
Starting with SGI Origin machines nearly every new SGI ASIC contains an 1-Wire master. They are used for attaching One-Wire prom devices, which contain information about part numbers, revision numbers, serial number etc. and MAC addresses for ethernet interfaces. This patch adds a master driver to support this IP block. It also adds an extra field dev_id to struct w1_bus_master, which could be in used in slave drivers for creating unique device names.

2019-09-04can: add support of SAE J1939 protocolThe j1939 authors
SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world. J1939, ISO 11783 and NMEA 2000 all share the same high level protocol. SAE J1939 can be considered the replacement for the older SAE J1708 and SAE J1587 specifications.

Extend Intel Stratix10 service layer driver to support new RSU notify and MAX_RETRY with watchdog event. RSU is used to provide our customers with protection against loading bad bitstream onto their devices when those devices are booting from flash RSU notifies provides users with an API to notify the firmware of the state of hard processor system. To deal with watchdog event, RSU provides a way for user to retry the current running image several times before giving up and starting normal RSU failover flow.

2019-09-04can: make use of preallocated can_ml_priv for per device struct ↵Marc Kleine-Budde
can_dev_rcv_lists This patch removes the old method of allocating the per device protocol specific memory via a netdevice_notifier. This had the drawback, that the allocation can fail, leading to a lot of null pointer checks in the code. This also makes the live cycle management of this memory quite complicated. This patch switches from the allocating the struct can_dev_rcv_lists in a NETDEV_REGISTER call to using the dev->ml_priv, which is allocated by the driver since the previous patch.

2019-09-04can: introduce CAN midlayer private and allocate it automaticallyMarc Kleine-Budde
This patch introduces the CAN midlayer private structure ("struct can_ml_priv") which should be used to hold protocol specific per device data structures. For now it's only member is "struct can_dev_rcv_lists". The CAN midlayer private is allocated via alloc_netdev()'s private and assigned to "struct net_device::ml_priv" during device creation. This is done transparently for CAN drivers using alloc_candev(). The slcan, vcan and vxcan drivers which are not using alloc_candev() have been adopted manually. The memory layout of the netdev_priv allocated via alloc_candev() will looke like this: +-------------------------+ | driver's priv | +-------------------------+ | struct can_ml_priv | +-------------------------+ | array of struct sk_buff | +-------------------------+ Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

2019-09-04tty: serial: Add linflexuart driver for S32V234Stefan-gabriel Mirea
Introduce support for LINFlex driver, based on: - the version of Freescale LPUART driver after commit b3e3bf2ef2c7 ("Merge 4.0-rc7 into tty-next"); - commit abf1e0a98083 ("tty: serial: fsl_lpuart: lock port on console write"). In this basic version, the driver can be tested using initramfs and relies on the clocks and pin muxing set up by U-Boot. Remarks concerning the earlycon support: - LinFlexD does not allow character transmissions in the INIT mode (see section 47.4.2.1 in the reference manual[1]). Therefore, a mutual exclusion between the first linflex_setup_watermark/linflex_set_termios executions and linflex_earlycon_putchar was employed and the characters normally sent to earlycon during initialization are kept in a buffer and sent afterwards. - Empirically, character transmission is also forbidden within the last 1-2 ms before entering the INIT mode, so we use an explicit timeout (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to linflex_setup_watermark. - U-Boot currently uses the UART FIFO mode, while this driver makes the transition to the buffer mode. Therefore, the earlycon putchar function matches the U-Boot behavior before initializations and the Linux behavior after.
